ANDREW J. BAKER, OF FORT WAYNE, INDIANA.

. DRY-SPRAY GUN.

Specification of Letters Patent.

Patented May 15, 191 '7.

Application filed November 23, 1916. Serial No. 133,081.

- To all w hom may con camp Be it known that I, ANDREW J. BAKER, acitizen of the United States, residing at Fort Wayne, in the county ofAllen and State of Indiana, have invented certainnew and usefulImprovements in Dry-Spray Guns; and I do declare the following to be afull,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the.

same.

My invention has for its object to provide a simple type of bell mouthgun carried by" a vertical staff and adapted for use in distributingpowder over the leaves of trees infested with insects to beexterminated.

With the foregoing general object in view, the invention resides incertain novel features of construction and in unique combinations ofparts to be hereinafter fully described and claimed, the descriptivematter being supplemented by the accompanying drawing which constitutesa part of this application, and in which:

Figure 1 is a side elevation of the improved gun in use;

Fig. 2 is a central longitudinal section thereof; and r Fig. 3 is an endelevation.

In the drawing above briefly described,

the numeral 1 has reference to a vertically elongated bodyhaving itsupper end increased in size to form a head 2 and having said head formedwith a socket 3 opening through its upper end, this end being reduced at4 and externally threaded to receive an internally threaded ferrule 5 onthe lower end of a short bell mouth barrel 6,

Q said barrel being preferably of funnel shape as shown. The barrel 6 isadapted to contain powder to be used in exterminating insects, while thesocket 3 is intended to be packed with explosive powder of any suitablemanufacture.

A port 7 leads through the lower end of the head 2 and communicates withthe socket 3, a boss 8 being provided at the outer end of. said port toreceive thereon a percussion cap 9 to be fired by a hammer 10 .pivotallymounted at 11 in a vertical slot 12 with which the body 1 is formed,said slot opening through opposite sides of said body as shown.

A spring 13 is provided for throwing the hammer 10 against the'cap 9,and for holding said hammer retracted against the tension of saidspring, a locking lever 14 is prov ded, sald lever being disposed toactive position by an appropriate spring 15. The ever 14 may be trippedat will to release the hammer 10 by a trigger 16.

The lower end of the body 1 has formed integrally therewith anexternally threaded plug 17 received in a socket 18 on the upper end ofa ferrule 19 within which the upper end of a' vertical stafi 20 issecured, said staif be1ng of a length to permit the gun to fireltscontents against the under sides of the leaves which are infested withinsects to be destroyed. For the purpose of trippmg the trlgger 16 whichis in most cases out of reach when the device is in operation, a cord orthe like 21 depends from said trigger as shown.

By constructing the improved device in the manner shown and described itmay be easlly and inexpensively manufactured and marketed, yet will bean effective tool for dry spraymg, 1t belng particularly advantageous 1nv1ew of the fact that by its constructlon, the insect powder may bedirected agalnst the under sides of the leaves, it being here that theinsects collect and breed most prolifically. On account of theseadvantages, the construction shown and described constitutes thepreferred form of the device, but it is to be understood that within thescope of the invention as claimed, numerous changes may be made Withoutsacrificing the principal advantages.

' I claim:

An insect powder gun comprising a vertically elongated body having itsupper end enlarged in the form of a head, said head having in its upperend a cavity-to receive an explosive powder, said end of the head beingreduced and externally threaded, a short funnel-shaped barrel having atits lower contracted end an integral ferrule threaded on said reducedend of the head, said barrel being adapted to contain the insect powder,the aforesaid head being formed in its lower end with a port leadingfrom the cavity, and the body having a vertically elongated slot openingthrough its sides, a hammer mounted in said slot and adapted to strikeand explode a percussion mer retracted against the tension of itsspring, a trigger for releasing said locking In testimony whereof I havehereunto set member, an externally threaded boss on the my hand in thepresence of two subscribing 10 lower'end of the aforesaid body, a.socket in Witnesses. which said boss is received, and a vertical staflcarrying said socket on its upper end,

said staff being of a length toposition the Witnesses: barrel of the gunbeneath the leaves of trees JOSEPH D. BYANSKIE, infested with theinsects to be exterminated. CLEM J. Nonn.
